Amazon web services AWS:Boto3配置存储桶生命周期-XML格式错误

下面的代码应该在bucket/bucket列表上启用版本控制，然后设置

但是，每当我运行此命令时，都会出现以下错误：

  File "putVersioning.py", line 42, in <module>
    'NoncurrentDays': 30
  File "/home/user/.local/lib/python2.7/site-packages/botocore/client.py", line 253, in _api_call
    return self._make_api_call(operation_name, kwargs)
  File "/home/user/.local/lib/python2.7/site-packages/botocore/client.py", line 557, in _make_api_call
    raise error_class(parsed_response, operation_name)
botocore.exceptions.ClientError: An error occurred (MalformedXML) when calling the PutBucketLifecycleConfiguration operation: The XML you provided was not well-formed or did not validate against our published schema

文件“putVersioning.py”，第42行，在
“非当前日”：30
文件“/home/user/.local/lib/python2.7/site packages/botocore/client.py”，第253行，在api调用中
返回self.\u make\u api\u调用（操作名称，kwargs）
文件“/home/user/.local/lib/python2.7/site packages/botocore/client.py”，第557行，在make\u api\u调用中
引发错误\u类（解析的\u响应、操作\u名称）
botocore.exceptions.ClientError:调用PutBucketLifecycleConfiguration操作时发生错误（格式错误的Dxml）：您提供的XML格式不正确，或者未根据发布的架构进行验证

据我所知，一切看起来都是正确的？

根据文档，您需要添加过滤元件，这是Amazon API所要求的，令人困惑的是，boto不需要。我添加了弃用的Prefix参数，而不是Filter，它似乎也在工作。

Hah！非常感谢。我很确定我的语法是正确的。谢谢你的帮助！
